Solderless directly written heating elements

ABSTRACT

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit may simulate a cigarette. A flow of electrical power may be coupled through solderless pressure contacts to activate a heating element. When the unit is activated, and the user provides suction, the liquid to be vaporized may be vaporized by an atomizer assembly. Vapors may then be aspirated by the user through an oral aspiration tube, where they may be inhaled.

TECHNICAL FIELD

This invention relates to personal vapor inhaling units and more particularly to an atomizer/vaporizer of an electronic flameless vapor inhaler unit that may simulate a cigarette or deliver nicotine and other medications to the oral mucosa, pharyngeal mucosa, tracheal, and pulmonary membranes.

BACKGROUND

An alternative to smoked tobacco products, such as cigarettes, cigars, or pipes is a personal vaporizer. Inhaled doses of heated and atomized flavor provide a physical sensation similar to smoking. However, because a personal vaporizer is typically electrically powered, no tobacco, smoke, or combustion is usually involved in its operation. For portability, and to simulate the physical characteristics of a cigarette, cigar, or pipe, a personal vaporizer may be battery powered. In addition, a personal vaporizer may be loaded with a nicotine bearing substance and/or a medication bearing substance. The personal vaporizer may provide an inhaled dose of nicotine and/or medication by way of the heated and atomized substance. Thus, personal vaporizers may also be known as electronic cigarettes, or e-cigarettes. Personal vaporizers may be used to administer flavors, medicines, drugs, or substances that are vaporized and then inhaled.

DETAILED DESCRIPTION

In an embodiment a personal vaporizer unit comprises a mouthpiece configured for contact with the mouth of a person. At least part of this mouthpiece has an antimicrobial surface. This mouthpiece may also comprise silicone rubber, thermoplastic elastomer, organosilane, silver impregnated polymer, silver impregnated thermoplastic elastomer, and/or polymer. The mouthpiece may be removed from the personal vaporizing for washing or replacement, without using a tool. The mouthpiece may be provided in different colors. Designs or other patterns may be visible on the outside of the mouthpiece.

In an embodiment, a personal vaporizer unit comprises a first conductive surface configured to contact a first body part of a person holding the personal vaporizer unit, and a second conductive surface, conductively isolated from the first conductive surface, configured to contact a second body part of the person. When the personal vaporizer unit detects a change in conductivity between the first conductive surface and the second conductive surface, a vaporizer is activated to vaporize a substance so that the vapors may be inhaled by the person holding unit. The first body part and the second body part may be a lip or parts of a hand(s). The two conductive surfaces may also be used to charge a battery contained in the personal vaporizer unit. The two conductive surfaces may also form, or be part of, a connector that may be used to output data stored in a memory.

In an embodiment, a personal vaporizer unit comprises a chamber configured to receive a cartridge. The cartridge may hold a substance to be vaporized. The chamber may be configured at the distal end of the personal vaporizer unit. A user may inhale the vaporized substance at the proximal end of the personal vaporizer unit. At least one space between the exterior surface of the cartridge, and an interior surface of the chamber, may define a passage for air to be drawn from outside the personal vaporizer unit, near the distal end, through the personal vaporizer unit to be inhaled by the user along with the vaporized substance. The personal vaporizer unit may also include a puncturing element that breaks a seal on the cartridge to allow a substance in the cartridge to be vaporized. An end surface of the cartridge may be translucent to diffuse light produced internally to the personal vaporizer unit. The translucent end may be etched or embossed with letters, symbols, or other indicia that are illuminated by the light produced internally to the personal vaporizer unit.

In an embodiment, a personal vaporizer unit comprises a first wick element and a second wick element having a porous ceramic. The first wick element is adapted to directly contact a liquid held in a reservoir. The reservoir may be contained by a cartridge that is removable from the personal vaporizer unit. A heating element is disposed through the second wick element. An air gap is defined between the first wick element and the second wick element with the heating element exposed to the air gap. Air enters the first wick element through a hole in a housing holding the first wick element.

In an embodiment, a personal vaporizer unit comprises a light source internal to an opaque cylindrical housing that approximates the appearance of a smoking article. A cylindrical light tube is disposed inside the opaque cylindrical housing to conduct light emitted by the light source to an end of the opaque cylindrical housing. This allows the light to be visible outside of the opaque cylindrical housing of the vaporizer.

In an embodiment, a personal vaporizer unit comprises a microprocessor, memory, and a connector. The connector outputs data stored in the memory. The microprocessor may gather, and store in the memory, information including, but not limited to, the number of cycles the device has been triggered, the duration of the cycles, the number cartridges of fluid that are delivered. The microprocessor may also gather and store times and dates associated with the other information gathered and stored. The microprocessor may detect an empty cartridge by detecting a specific change in resistance between a wick and a housing that is equivalent to a “dry wick”, and thus signifies an empty cartridge.

In an embodiment, a case comprises a cradle adapted to hold a personal vaporizer unit. The personal vaporizer unit has dimensions approximating a smoking article. The case includes a battery and at least two contacts. The two contacts may form an electrical contact with the personal vaporizer unit when the personal vaporizer unit is in the cradle. The two contacts may conduct charge from the battery to the personal vaporizer unit to charge the personal vaporizer unit. The case may also download and store data retrieved from the personnel vaporizing unit. The case may download and store this data via the at least two contacts. The case may send this data to a computer via wired or wireless links. The case may have more than one cradle and sets of contacts (e.g., two sets of two contacts in order to hold and charge two personal vaporizer units).

FIG. 1 is a perspective view of a personal vaporizer unit. In FIG. 1, personal vaporizer unit 100 comprises outer main shell 102, mouthpiece cover 114, mouthpiece 116, and mouthpiece insulator 112. The mouthpiece 116 and mouthpiece cover 114 define the proximal end of personal vaporizer unit 100. The opposite end of personal vaporizer unit 100 will be referred to as the distal end. A cartridge 150 may be inserted into the distal end of personal vaporizer unit 100. Cartridge 150 may hold the substance to be vaporized by personal vaporizer unit 100. The substance after vaporizing may be inhaled by a user holding the personal vaporizer unit 100. The substance may be in the form of a liquid or gel.

FIG. 2 is a side view of a personal vaporizer unit. FIG. 2 illustrates personal vaporizer unit 100 as viewed from the side. FIG. 2 illustrates personal vaporizer unit 100 comprising outer main shell 102, mouthpiece cover 114, mouthpiece 116, and mouthpiece insulator 112. FIG. 2 also illustrates cartridge 150 inserted into the distal end of personal vaporizer unit 100.

FIG. 3 is an end view of the proximal end of a personal vaporizer unit. FIG. 3 shows the proximal end view of personal vaporizer unit 100 comprising mouthpiece cover 114. FIG. 4 is an end view of the distal end of a personal vaporizer unit. FIG. 4 shows the distal end view personal vaporizer unit 100 comprising the visible portion of cartridge 150. FIG. 4A is an alternative end view of personal vaporizer unit 100 comprising a visible portion of cartridge 150 that has visible logos, letters, or other symbols. These visible logos, letters, or other symbols may be illuminated or backlit by a light source internal to the personal vaporizer unit 100. The light source may be activated intermittently under the control of a microprocessor or other electronics internal to personal vaporizer unit 100. The light source may be activated in such a manner as to simulate the glowing ash of a cigar or cigarette.

FIG. 5 is a figure map of FIGS. 6 and 7. FIG. 6 is a cross-section of the proximal portion of a personal vaporizer unit along the cut line shown in FIG. 2. In FIG. 6, the proximal portion of personal vaporizer unit 100 comprises mouthpiece cover 114, mouthpiece 116, mouthpiece insulator 112, outer main shell 102, battery support 106, and battery 104. The mouthpiece cover 114 surrounds and is engaged with the distal end of mouthpiece 116. Mouthpiece 116 and outer main shell 102 are preferably made of an electrically conductive material(s). Mouthpiece 116 is separated from outer main shell 102 by mouthpiece insulator 112. Mouthpiece 116 and outer main shell 102 are thus electrically isolated from each other by mouthpiece insulator 112.

In an embodiment, personal vaporizer unit 100 is configured such that other main shell 102 comprises a first conductive surface configured to contact a first body part of a person holding personal vaporizer unit 100. Mouthpiece 116 comprises a second conductive surface, which is conductively isolated from the first conductive surface. This second conductive surface is configured to contact a second body part of the person. When personal vaporizer unit 100 detects a change in conductivity between the first conductive surface and the second conductive surface, a vaporizer internal to personal vaporizer unit 100 is activated to vaporize a substance in cartridge 150 so that the vapors may be inhaled by the person holding personal vaporizer unit 100. The first body part and the second body part may be a lip or parts of a hand(s). The two conductive surfaces of outer main shell 102 and mouthpiece 116, respectively, may also be used to charge battery 104 contained in the personal vaporizer unit 100. The two conductive surfaces of outer main shell 102 and mouthpiece 116, respectively, may also be used to output (or input) data stored (or to be stored) in a memory (not shown).

Battery support 106 functions to hold battery 104 in a position which is fixed relative to our main shell 102. Battery support 106 is also configured to allow air and vaporized substance to pass from the distal end of personal vaporizer unit 100 past battery 104 along one or more passageways. After air and the vapors of the vaporized substance pass by battery 104, they may pass through openings in mouthpiece 116, mouthpiece cover 114, and mouthpiece insulator 112, to be inhaled by a user.

FIG. 7 is a cross-section of the distal portion of a personal vaporizer unit along the cut line shown in FIG. 2. In FIG. 7, the distal end portion of personal vaporizer unit 100 comprises outer main shell 102, light pipe sleeve 140, and atomizer housing 132, distal wick 134, proximal wick 136, PC board 123, PC board 124, spacer 128, and main housing 160. FIG. 7 also illustrates cartridge 150 inserted into the distal end of personal vaporizer unit 100. As can be seen in FIG. 7, cartridge 150 may hold a substance (e.g., a liquid or gel) in direct contact with distal wick 134. The substance may be drawn through distal wick 134 to be vaporized inside atomizer assembly. The atomizer assembly comprises atomizer housing 132, distal wick 134, proximal wick 136, and a heating element (not shown).

FIG. 8 is an exploded side view of components of a personal vaporizer unit. FIG. 9 is an exploded cross-section of components of a personal vaporizer unit along the cut line shown in FIG. 2.

In FIGS. 8 and 9, personal vaporizer unit 100 comprises (from left to right) mouthpiece cover 114, mouthpiece 116, mouthpiece insulator 112, battery 104, battery support 106, PC board 123, spacer 128, PC board 124, main housing 160, proximal wick 136, distal wick 134, atomizer housing 132, light pipe sleeve 140, and cartridge 150. Mouthpiece cover 114 surrounds and covers the proximal end of mouthpiece 116. The distal end of mouthpiece 116 is inserted into mouthpiece insulator 112. Battery 104 is held in place by battery support 106. PC board 123, spacer 128 and PC board 124 are disposed within main housing 160. Proximal wick 136 and distal wick 134 are disposed within atomizer housing 132.

Atomizer housing 132 (and therefore proximal wick 136, distal wick 134) are disposed inside light pipe sleeve 140 and main shell 102. (Note: for clarity, main shell 102 is not shown in FIGS. 8 and 9.) Light pipe sleeve 140 is disposed within main shell 102. Light pipe sleeve 140 is positioned such that light emitted from a light source mounted on PC board 124 may be conducted via light pipe sleeve 140 to a location where it is visible on the outside of personal vaporizer unit 100.

Cartridge 150 is disposed within light pipe sleeve 140. When assembled, a substance contained within cartridge 150 is held in direct contact with distal wick 134. When cartridge 150 is inserted into personal vaporizer unit 100 atomizer housing 132 or distal wick 134 may puncture a seal or cap that contains the substance to be vaporized within cartridge 150. Once punctured, the substance held within a reservoir of cartridge 150 may come in direct contact with distal wick 134.

FIG. 10 is a perspective view of a mouthpiece cover of a personal vaporizer unit. FIG. 11 is a distal end view of the mouthpiece cover of FIG. 10. FIG. 12 is a cross-section of the mouthpiece cover along the cut line shown in FIG. 11. As can be seen in FIGS. 10-12, mouthpiece cover 114 has an opening 114-1 that allows air and the vaporized substance to be drawn through mouthpiece cover 114. Mouthpiece cover 114 is configured for contact with the mouth of a person. In an embodiment, at least part of the mouthpiece cover has an antimicrobial surface. This antimicrobial surface of mouthpiece cover 114 may comprise, but is not limited to: silicone rubber, thermoplastic elastomer, organosilane, silver impregnated polymer, silver impregnated thermoplastic elastomer, and/or polymer. Mouthpiece cover 114 is also configured to be removable from personal vaporizer unit 100 by a user without the use of tools. This allows mouthpiece cover 114 to be replaced and/or washed. In an embodiment, mouthpiece cover 114 may be held in place on personal vaporizer unit 100 by annular ridge 114-2 which interfaces with a groove on mouthpiece 116 of personal vaporizer unit 100 to secure mouthpiece cover 114 in place. In another embodiment, mouthpiece cover 114 may be held in place on personal vaporizer unit 100 by a friction fit.

FIG. 13 is a perspective view of a mouthpiece of a personal vaporizer unit. FIG. 14 is a side view of the mouthpiece of FIG. 13. FIG. 15 is a cross-section of the mouthpiece along the cut line shown in FIG. 14. As can be seen in FIGS. 13-15, mouthpiece 116 has a passageway 116-1 that allows air and the vaporized substance to be drawn through mouthpiece 116. Mouthpiece 116 may comprise a conductive surface or material configured to contact a first body part of a person holding personal vaporizer unit 100. This first body part may be part of a hand, or at least one lip of the person holding personal vaporizer unit 100. In an embodiment, mouthpiece 116 has an annular groove 116-2 around an outside surface. This groove is configured to receive annular ridge 114-2. Thus, annular groove 116-2 helps secure mouthpiece cover 114 to personal vaporizer unit 100.

FIG. 16 is a perspective view of a mouthpiece insulator of a personal vaporizer unit. FIG. 17 is a distal end view of the mouthpiece insulator of FIG. 16. FIG. 18 is a side view of the mouthpiece insulator of FIG. 16. FIG. 19 is a cross-section of the mouthpiece insulator along the cut line shown in FIG. 18. As discussed previously, mouthpiece insulator 112 is disposed between main shell 102 and mouthpiece 116. As can be seen in FIGS. 16-18, mouthpiece insulator 112 has a passageway 112-1 that allows air and the vaporized substance to be drawn through mouthpiece insulator 112. Because mouthpiece insulator 112 is disposed between main shell 102 and mouthpiece 116, mouthpiece insulator 112 can electrically isolate main shell 102 and mouthpiece 116. Thus, in an embodiment, mouthpiece insulator 112 comprises, or is made of, a non-electrically conductive material. This electrical isolation between main shell 102 and mouthpiece 116 allow electrical impedance changes between main shell 102 and mouthpiece 116 to be detected.

For example, a first conductive surface on mouthpiece 116 may be configured to contact a first body part of a person holding personal vaporizer unit 100. A second conductive surface on main shell 102 (which is conductively isolated from said first conductive surface by mouthpiece insulator 112) may be configured to contact a second body part of the person. Personal vaporizer unit 100 may then activate in response to detecting a change in conductivity between the first conductive surface and the second conductive surface. In an embodiment, this change in conductivity may comprise a drop in impedance between the first conductive surface and the second conductive surface. In an embodiment, the change in conductivity may comprise a change in capacitance between the first conductive surface and the second conductive surface. The first body part may be a finger. The second body part may be a lip. The second body part may be a second finger. In an embodiment, the first conductive surface and the second conductive surfaces may be used to pass a charging current to battery 104. The first and second conductive surfaces may also be used to transfer data to or from personal vaporizer unit 100.

FIG. 20 is a perspective view of a main housing of a personal vaporizer unit. FIG. 21 is a distal end view of the main housing of FIG. 20. FIG. 22 is a proximal end view of the main housing of FIG. 20. FIG. 23 is a side view of the main housing of FIG. 20. FIG. 24 is a cross-section of the main housing along the cut line shown in FIG. 23. Main housing 160 is configured to hold PC-boards 123 and 124, and spacer 128. Main housing 160 is configured to fit within main shell 102 via a friction fit. Main housing 160 has several holes 166 that allow light generated by a light source(s) on PC-board 124 to pass. Once this light passes through holes 166, it may be coupled into light pipe sleeve 140 where it is conducted to a visible location on the outside of personal vaporizer unit 100.

Main housing 160 also has a hole 165 that allows an electrical conductor (not shown) to run from PC-board 123 or PC-board 124 through main housing 160. This electrical conductor may be, or connect to, a heating element (not shown). This heating element may help vaporize the substance to be inhaled by the user of personal vaporizer unit 100. This heating element may be controlled by circuitry on PC-board 123 or PC-board 124. This heating element may be activated in response to a change in conductivity between the first conductive surface and the second conductive surface, described previously.

The exterior of main housing 160 may also have a flat surface 164 (or other geometry) forming a galley that is configured to allow the vaporized substance and air to pass between the main housing 160 and the main shell 102. Once the vaporized substance and air pass by main housing 160, they may travel through passageway 112-1, passageway 116-1, and opening 114-1 to be inhaled by a user of personal vaporizer unit 100. The exterior of main housing 160 may also have one or more standoffs 167 (or other geometries) that are configured to allow air and the vaporized substance to reach the passageway formed by flat surface 164 and main shell 102.

FIG. 25 is a perspective view of a main housing of a personal vaporizer unit. FIG. 26 is a second perspective view of the main housing of FIG. 25. FIG. 27 is a distal end view of the main housing of FIG. 25. FIG. 28 is a proximal end view of the main housing of FIG. 25. FIG. 29 is a side view of the main housing of FIG. 25. FIG. 30 is a cross-section of the main housing along the cut line shown in FIG. 29. Main housing 260 may be used as an alternative embodiment to main housing 160.

Main housing 260 is configured to hold PC-boards 123 and 124, and spacer 128. Main housing 260 is configured to fit within main shell 102 via a friction fit. Main housing 260 has several holes 266 that allow light generated by a light source(s) on PC-board 124 to pass. Once this light passes through holes 266, it may be coupled into light pipe sleeve 140 where it is conducted to a visible location on the outside of personal vaporizer unit 100.

Main housing 260 also has a hole 265 that allows an electrical conductor (not shown) to run from PC-board 123 or PC-board 124 through main housing 260. This electrical conductor may be, or connect to, a heating element (not shown). This heating element may help vaporize the substance to be inhaled by the user of personal vaporizer unit 100. This heating element may be controlled by circuitry on PC-board 123 or PC-board 124. This heating element may be activated in response to a change in conductivity between the first conductive surface and the second conductive surface, described previously.

The exterior of main housing 260 may also have flat surfaces 264 (or other geometry) that form a galley that is configured to allow the vaporized substance and air to pass between the main housing 260 and the main shell 102. Once the vaporized substance and air pass by main housing 260, they may travel through passageway 112-1, passageway 116-1, and opening 114-1 to be inhaled by a user of personal vaporizer unit 100. The exterior of main housing 260 may also have one or more standoffs 267 (or other geometries) that are configured to allow air and the vaporized substance to reach the passageway formed by flat surfaces 264 and main shell 102.

FIG. 31 is a perspective view of a printed circuit board assembly of a personal vaporizer unit. FIG. 32 is a distal end view of the PCB assembly of FIG. 31. FIG. 33 is a perspective exploded view of the PCB assembly of FIG. 31. FIG. 34 is a side exploded view of the PCB assembly of FIG. 31. As can be seen in FIGS. 31-34, the PCB assembly is comprised of PC-board 123 and PC-board 124 separated by a spacer 128. PC-board 124 may have mounted upon it light emitting diodes (LEDs) 125-127 or other light sources. LEDs 125-127 are configured and positioned such that when they produce light, that light passes through holes 166 or 266 in main housings 160 and 260, respectively. This light may then be conducted by light pipe sleeve 140 to a location where it will be visible exterior to personal vaporizer unit 100.

PC-board 123 may have mounted on it a microprocessor, memory, or other circuitry (not shown) to activate or otherwise control personal vaporizer unit 100. This microprocessor may store data about the operation of personal vaporizer unit 100 in the memory. For example, the microprocessor may determine and store the number of cycles personal vaporizer unit 100 has been triggered. The microprocessor may also store a time and/or date associated with one or more of these cycles. The microprocessor may cause this data to be output via a connector. The connector may be comprised of the first and second conductive surfaces of mouthpiece 116 and/or main shell 102.

In an embodiment, the microprocessor may determine a duration associated with various cycles where personal vaporizer unit 100 has been triggered. These durations (or a number based on these duration, such as an average) may be stored in the memory. The microprocessor may cause these numbers to be output via the connector. The microprocessor may determine an empty cartridge condition and stores a number associated with a number of times said empty cartridge condition occurs. The microprocessor, or other circuitry, may determine an empty cartridge condition determined based on a resistance between atomizer housing 132 or 232 and a wick 134, 234, 136, or 236. The microprocessor may also store a time and/or date associated with one or more of these empty cartridge conditions. The number of times an empty cartridge condition is detected, and or times and/or dates associated with these empty cartridge conditions may be output via the connector.

Battery 104, PC-board 123, PC-board 124, and all electronics internal to personal vaporizer unit 100 may be sealed in a plastic or plastic and epoxy compartment within the device. This compartment may include main housing 160 or 260. All penetrations in this compartment may be sealed. Thus, only wires will protrude from the compartment. The compartment may be filled with epoxy after the assembly of battery 104, PC-board 123, PC-board 124, and LEDs 125-127. The compartment may be ultrasonically welded closed after assembly of battery 104, PC-board 123, PC-board 124, and LEDs 125-127. This sealed compartment is configured such that all vapor within personal vaporizer unit 100 does not come in contact with the electronics on PC-boards 123 or 124.

FIG. 35 is a perspective view of a proximal wick element of a personal vaporizer unit. FIG. 35A is a perspective view of a heating element disposed through a proximal wick element of a personal vaporizer unit. FIG. 35B is a perspective view of a heating element of a personal vaporizer unit. FIG. 36 is a distal end view of the wick element of FIG. 35. FIG. 37 is a cross-section of the wick element along the cut line shown in FIG. 35. Proximal wick 136 is configured to fit within atomizer housing 132. As can be seen in FIGS. 35-37, proximal wick 136 includes internal wire passageway 136-1 and external wire passageway 136-2. These wire passageways allows a conductor or a heating element 139 to be positioned through proximal wick 136 (via internal wire passageway 136-1). This conductor or heating element 139 may also be positioned in external wire passageway 136-2. Thus, as shown in FIG. 35A, a conductor or heating element 139 may be wrapped around a portion of proximal wick 136 by running the conductor or heating element 139 through internal wire passageway 136-1, around the distal end of proximal wick 136, and through external wire passageway 136-2 to return to approximately its point of origin. The heating element 139 may, when personal vaporizer 100 is activated, heat proximal wick 136 in order to facilitate vaporization of a substance.

FIG. 38 is a perspective view of a distal wick element of a personal vaporizer unit. FIG. 39 is a distal end view of the wick element of FIG. 38. FIG. 40 is a cross-section of the wick element along the cut line shown in FIG. 39. Distal wick 134 is configured to fit within atomizer housing 132. As can be seen in FIGS. 38-40, distal wick 134 comprises two cylinders of different diameters. A chamfered surface transitions from the smaller diameter of the distal end of distal wick 134 to a larger diameter at the proximal end of distal wick 134. The cylinder at the distal end terminates with a flat surface end 134-1. This flat surface end 134-1 is the end of distal wick 134 is a surface that is placed in direct contact with a substance to be vaporized when cartridge 150 is inserted into the distal end of personal vaporizer 100. The proximal end of distal wick 134 is typically in contact with proximal wick 136. However, at least a part of proximal wick 136 and distal wick 134 are separated by an air gap. When distal wick 134 and proximal wick 136 are used together, this air gap is formed between distal wick 134 and proximal wick 136 by stand offs 136-3 as shown in FIG. 37.

FIG. 41 is a perspective view of a distal wick element of a personal vaporizer unit. FIG. 42 is a distal end view of the wick element of FIG. 41. FIG. 43 is a cross-section of the wick element along the cut line shown in FIG. 42. Proximal wick 234 may be used as an alternative embodiment to distal wick 134. Proximal wick 234 is configured to fit within atomizer housing 232. As can be seen in FIGS. 41-43, proximal wick 234 comprises two cylinders of different diameters, and a cone or pointed end 234-1. A chamfered surface transitions from the smaller diameter of the distal end of proximal wick 234 to a larger diameter at the proximal end of proximal wick 234. The cylinder at the distal end terminates with a pointed end 234-1. This pointed end 234-1 is the end of proximal wick 234 that is in direct contact with a substance to be vaporized. This pointed end 234-1 may also break a seal on cartridge 150 to allow the substance to be vaporized to come in direct contact with proximal wick 234. The proximal end of proximal wick 234 is typically in contact with proximal wick 136. However, at least a part of proximal wick 136 and proximal wick 234 are separated by an air gap. When distal wick 134 and proximal wick 236 are used together, this air gap is formed between proximal wick 234 and proximal wick 136 by stand offs 136-3 as shown in FIG. 37.

FIG. 44 is a perspective view of an atomizer housing of a personal vaporizer unit. FIG. 45 is a distal end view of the atomizer housing of FIG. 44. FIG. 46 is a side view of the atomizer housing of FIG. 44. FIG. 47 is a top view of the atomizer housing of FIG. 44. FIG. 48 is a cross-section of the atomizer housing along the cut line shown in FIG. 47. Atomizer housing 132 is configured to fit within main shell 102. As can be seen in FIGS. 44-48, atomizer housing 132 comprises roughly two cylinders of different diameters. A chamfered surface 132-3 transitions from the smaller diameter of the distal end of atomizer housing 132 to a larger diameter at the proximal end of atomizer housing 132. The larger diameter at the proximal end of atomizer housing 132 is configured to be press fit into light pipe sleeve 140. The cylinder at the distal end terminates with a spade shaped tip 132-2. This spade shaped tip 132-2 may break a seal on cartridge 150 to allow the substance to be vaporized to come in direct contact with distal wick 134. Other shaped tips are possible (e.g., needle or spear shaped).

Chamfered surface 132-3 has one or more holes 132-1. These holes allow air to pass, via suction, through atomizer housing 132 into distal wick 134. This suction may be supplied by the user of personal vaporizer 100 sucking or inhaling on mouthpiece cover 114 and/or mouthpiece 116. The air that is sucked into distal wick 134 enters distal wick 134 on or near the chamfered surface between the two cylinders of distal wick 134. The air that is sucked into distal wick 134 displaces some of the substance being vaporized that has been absorbed by distal wick 134 causing it to be atomized as it exits distal wick 134 into the air gap formed between distal wick 134 and proximal wick 136. The heating element disposed around proximal wick 136 may then vaporize at least some of the atomized substance. In an embodiment, one or more holes 132-1 may range in diameter between 0.02 and 0.0625 inches.

In an embodiment, placing holes 132-1 at the leading edge of the chamfered surface places a set volume of the substance to be vaporized in the path of incoming air. This incoming air has nowhere to go but through the large diameter (or “head”) end of the distal end wick 134. When the air enters this area in distal end wick 134 it displaces the substance to be vaporized that is suspended in distal end wick 134 towards an air cavity between distal end wick 134 and proximal end wick 136. When the displaced substance to be vaporized reaches the surface of distal end wick 134, it is forced out of the wick by the incoming air and the negative pressure of the cavity. This produces an atomized cloud of the substance to be vaporized. In an embodiment, the diameter of the head of distal end wick 134 may be varied and be smaller than the diameter of the proximal end wick 136. This allows for a tuned volume of air to bypass proximal end wick 136 and directly enter the cavity between distal wick 134 and distal wick 136 without first passing through distal wick 136.

FIG. 49 is a perspective view of an atomizer housing of a personal vaporizer unit. FIG. 50 is a distal end view of the atomizer housing of FIG. 49. FIG. 51 is a side view of the atomizer housing of FIG. 49. FIG. 52 is a top view of the atomizer housing of FIG. 49. FIG. 53 is a cross-section of the atomizer housing along the cut line shown in FIG. 52. Atomizer housing 232 is an alternative embodiment, for use with proximal wick 234, to atomizer house 132. Atomizer housing 232 is configured to fit within main shell 102 and light pipe sleeve 140. As can be seen in FIGS. 49-53, atomizer housing 232 comprises roughly two cylinders of different diameters. A chamfered surface 232-3 transitions from the smaller diameter of the distal end of atomizer housing 232 to a larger diameter at the proximal end of atomizer housing 232. The larger diameter at the proximal end of atomizer housing 232 is configured to be press fit into light pipe sleeve 140. The cylinder at the distal end terminates with an open cylinder tip 232-2. This open cylinder tip 232-2 allows the pointed end 234-1 of proximal wick 234 to break a seal on cartridge 150 to allow the substance to be vaporized to come in direct contact with proximal wick 234.

Chamfered surface 232-3 has one or more holes 232-1. These holes allow air to pass, via suction, through atomizer housing 232 into proximal wick 234. The air that is sucked into proximal wick 234 enters proximal wick 234 on or near the chamfered surface between the two cylinders of proximal wick 234. The air that is sucked into proximal wick 234 displaces some of the substance being vaporized that has been absorbed by proximal wick 234 causing it to be atomized as it exits proximal wick 234 into the air gap formed between proximal wick 234 and proximal wick 136. The heating element disposed around proximal wick 136 may then vaporize at least some of the atomized substance being vaporized. In an embodiment, one or more holes 232-1 may range in diameter between 0.02 and 0.0625 inches.

In an embodiment, placing holes 232-1 at the leading edge of the chamfered surface places a set volume of the substance to be vaporized in the path of incoming air. This incoming air has nowhere to go but through the head of the distal end wick 234. When the air enters this area in distal end wick 234 it displaces the substance to be vaporized that is suspended in distal end wick 234 towards an air cavity between distal end wick 234 and proximal end wick 236. When the displaced substance to be vaporized reaches the surface of distal end wick 232, it is forced out of the wick by the incoming air and the negative pressure of the cavity. This produces an atomized cloud of the substance to be vaporized. In an embodiment, the diameter of the head of distal end wick 234 may be varied and be smaller than the diameter of the proximal end wick 236. This allows for a tuned volume of air to bypass distal wick 236 and directly enter the cavity between proximal wick 234 and distal wick 236 without first passing through distal wick 236.

FIG. 54 is a perspective view of an atomizer housing and wicks of a personal vaporizer unit. FIG. 55 is an exploded view of the atomizer housing, wire guides, and wicks of FIG. 54. FIG. 56 is a side view of the atomizer housing and wicks of FIG. 54. FIG. 57 is a distal end view of the atomizer housing and wicks of FIG. 54. FIG. 58 is a cross-section of the atomizer housing and wicks along the cut line shown in FIG. 57. The atomizer housing and wicks shown in FIGS. 54-58 is an alternative embodiment for use with proximal wick 236. The embodiment shown in FIGS. 54-58 use atomizer housing 232, proximal wick 234, proximal wick 236, wire guide 237, and wire guide 238. Proximal wick 236 is configured to fit within atomizer housing 232. As can be seen in FIGS. 54-58, proximal wick 236 includes internal wire passageway 236-1. This wire passageway 236-1 allows a conductor or a heating element (not shown) to be positioned through proximal wick 236 (via internal wire passageway 236-1). The conductor or heating element may be positioned around wire guide 237 and wire guide 238. Thus, a conductor or heating element may run the through wire passageway 236-1, around wire guides 237 and 238, and then back through wire passageway 236-1 to return to approximately its point of origin. The heating element may, when personal vaporizer unit 100 is activated, heat proximal wick 236 in order to facilitate vaporization of a substance.

FIG. 59 is a perspective view of the proximal end wick assembly of FIGS. 54-58. FIG. 59A is a perspective view showing a heating element disposed through the proximal end wick and around the wire guides of FIGS. 54-58. FIG. 59B is a perspective view of the heating element of a personal vaporizer unit. FIG. 60 is a distal end view of the wick element and wire guides of FIGS. 54-58. FIG. 61 is a cross-section of the wick element and wire guides along the cut line shown in FIG. 60. As can be seen in FIG. 59A, a conductor or heating element 239 may run through wire passageway 236-1, around wire guides 237 and 238, and then back through wire passageway 236-1 to return to approximately its point of origin.

In an embodiment, distal wicks 134, 234, and proximal wicks 136, 236, may be made of, or comprise, for example a porous ceramic. Distal wicks 134, 234, and proximal wicks 136, 236, may be made of, or comprise aluminum oxide, silicon carbide, magnesia partial stabilized zirconia, yttria tetragonal zirconia polycrystal, porous metal (e.g., steel, aluminum, platinum, titanium, and the like), ceramic coated porous metal, woven metal, spun metal, metal wool (e.g., steel wool), porous polymer, porous coated polymer, porous silica (i.e., glass), and/or porous Pyrex. Distal wicks 134, 234, and proximal wicks 136, 236, may be made of or comprise other materials that can absorb a substance to be vaporized.

The conductor or heating element that is disposed through proximal wick 136 or 236 may be made of, or comprise, for example: nickel chromium, iron chromium aluminum, stainless steel, gold, platinum, tungsten molybdenum, or a piezoelectric material. The conductor or heating element that is disposed through proximal wick 136 can be made of, or comprise, other materials that become heated when an electrical current is passed through them.

FIG. 62 is a perspective view of a light pipe sleeve of a personal vaporizer unit. FIG. 63 is an end view of the light pipe sleeve of FIG. 62. FIG. 64 is a cross-section of the light pipe sleeve along the cut line shown in FIG. 63. Light pipe sleeve 140 is configured to be disposed within main shell 102. Light pipe sleeve 140 is also configured to hold cartridge 150 and atomizer housing 132 or 232. As discussed previously, light pipe sleeve 140 is configured to conduct light entering the proximal end of light pipe sleeve 140 (e.g., from LEDs 125-127) to the distal end of light pipe sleeve 140. Typically, the light exiting the distal end of light pipe sleeve 140 will be visible from the exterior of personal vaporizer 100. The light exiting the distal end of light pipe sleeve 140 may be diffused by cartridge 150. The light exiting the distal end of light pipe sleeve 140 may illuminate characters and/or symbols drawn, printed, written, or embossed, etc., in an end of cartridge 150. In an embodiment, light exiting light pipe sleeve 140 may illuminate a logo, characters and/or symbols cut through outer main shell 102. In an embodiment, light pipe sleeve 140 is made of, or comprises, a translucent acrylic plastic.

FIG. 65 is a perspective view of a cartridge of a personal vaporizer unit. FIG. 66 is a proximal end view of the cartridge of FIG. 65. FIG. 67 is a side view of the cartridge of FIG. 65. FIG. 68 is a top view of the cartridge of FIG. 65. FIG. 69 is a cross-section of the cartridge along the cut line shown in FIG. 66. As shown in FIGS. 65-69, cartridge 150 comprises a hollow cylinder section with at least one exterior flat surface 158. The flat surface 158 forms, when cartridge 150 is inserted into the distal end of personal vaporizer unit 100, an open space between the exterior surface of the cartridge and an interior surface of light pipe sleeve 140. This space defines a passage for air to be drawn from outside personal vaporizer unit 100, through personal vaporizer unit 100 to be inhaled by the user along with the vaporized substance. This space also helps define the volume of air drawn into personal vaporizer unit 100. By defining the volume of air typically drawn into the unit, different mixtures of vaporized substance to air may be produced.

The hollow portion of cartridge 150 is configured as a reservoir to hold the substance to be vaporized by personal vaporizer unit 100. The hollow portion of cartridge 150 holds the substance to be vaporized in direct contact with distal wick 134 or 234. This allows distal wick 134 or 234 to become saturated with the substance to be vaporized. The area of distal wick 134 or 234 that is in direct contact with the substance to be vaporized may be varied in order to deliver different doses of the substance to be vaporized. For example, cartridges 150 with differing diameter hollow portions may be used to deliver different doses of the substance to be vaporized to the user.

Cartridge 150 may be configured to confine the substance to be vaporized by a cap or seal (not shown) on the proximal end. This cap or seal may be punctured by the end of atomizer housing 132, or the pointed end 234-1 of proximal wick 234.

When inserted into personal vaporizer unit 100, cartridge standoffs 157 define an air passage between the end of light pipe sleeve 140 and main shell 102. This air passage allows air to reach the air passage defined by flat surface 158.

The hollow portion of cartridge 150 also includes one or more channels 154. The end of these channels are exposed to air received via the air passage(s) defined by flat surface 158. These channels allow air to enter the hollow portion of cartridge 150 as the substance contained in cartridge 150 is drawn into a distal wick 134 or 234. Allowing air to enter the hollow portion of cartridge 150 as the substance contained in cartridge 150 is removed prevents a vacuum from forming inside cartridge 150. This vacuum could prevent the substance contained in cartridge 150 from being absorbed into distal wick 134 or 234.

In an embodiment, cartridge 150 may be at least partly translucent. Thus cartridge 150 may act as a light diffuser so that light emitted by one or more of LEDs 125-127 is visible external to personal vaporizer unit 100.

FIG. 70 is a side view of a battery of a personal vaporizer unit. FIG. 71 is an end view of the battery of FIG. 70. FIG. 72 is a perspective view of a battery support of a personal vaporizer unit. As can be seen in FIG. 72, battery support 106 does not form a complete cylinder that completely surrounds battery 104. This missing portion of a cylinder forms a passageway that allows air and the vaporized substance to pass by the battery from the atomizer assembly to the mouthpiece 116 so that it may be inhaled by the user.

FIG. 73 is a top perspective view of a personal vaporizer unit case. FIG. 74 is a bottom perspective view of a personal vaporizer unit case. Personal vaporizer case 500 is configured to hold one or more personal vaporizer units 100. Personal vaporizer case 500 includes a connector 510 to interface to a computer. This connector allows case 500 to transfer data from personal vaporizer unit 100 to a computer via connecter 510. Case 500 may also transfer data from personal vaporizer unit 100 via a wireless interface. This wireless interface may comprise an infrared (IR) transmitter, a Bluetooth interface, an 802.11 specified interface, and/or communicate with a cellular telephone network. Data from a personal vaporizer unit 100 may be associated with an identification number stored by personal vaporizer unit 100. Data from personal vaporizer unit 100 may be transmitted via the wireless interface in association with the identification number.

Personal vaporizer case 500 includes a battery that may hold charge that is used to recharge a personal vaporizer unit 100. Recharging of personal vaporizer unit 100 may be managed by a charge controller that is part of case 500.

When case 500 is holding a personal vaporizer unit 100, at least a portion of the personal vaporizer unit 100 is visible from the outside of case 500 to allow a light emitted by personal vaporizer unit 100 to provide a visual indication of a state of personal vaporizer unit 500. This visual indication is visible outside of case 500.

Personal vaporizer unit 100 is activated by a change in impedance between two conductive surfaces. In an embodiment, these two conductive surfaces are part of main shell 102 and mouthpiece 116. These two conductive surfaces may also be used by case 500 to charge battery 104. These two conductive surfaces may also be used by case 500 to read data out of personal vaporizer unit 100.

In an embodiment, when a user puts personal vaporizer unit 100 in his/her mouth and provides “suction,” air is drawn into personal vaporizer unit 100 though a gap between the end of main shell 102 and cartridge 150. In an embodiment, this gap is established by standoffs 157. Air travels down galley(s) formed by flat surface(s) 158 and the inner surface of light pipe sleeve 140. The air then reaches a “ring” shaped galley between atomizer housing 132, cartridge 150, and light pipe sleeve 140. Air travels to distal wick 134 via one or more holes 132-1, in chamfered surface(s) 132-3. Air travels to distal wick 234 via one or more holes 232-1, in chamfered surface(s) 232-3. Air is also allowed to enter cartridge 150 via one or more channels 154. This air entering cartridge 150 via channels 154 “back fills” for the substance being vaporized which enters distal wick 134. The substance being vaporized is held in direct contact with distal wick 134 or 234 by cartridge 150. The substance being vaporized is absorbed by and may saturate distal wick 134 or 234 and proximal wick 136 or 236.

The incoming air drawn through holes 132-1 displaces from saturated distal wick 134 the substance being vaporized. The displaced substance being vaporized is pulled from wick elements 134 into a cavity between distal wick 134 and 136. This cavity may also contain a heating element that has been heated to between 150-200° C. The displaced substance being vaporized is pulled from wick elements 134 in small (e.g., atomized) droplets. These atomized droplets are vaporized by the heating element.

In an embodiment, when a user puts personal vaporizer unit 100 in his/her mouth and provides “suction,” air is drawn into personal vaporizer unit 100 though a gap between the end of main shell 102 and cartridge 150. In an embodiment, this gap is established by standoffs 157. Air travels down galley(s) formed by flat surface(s) 158 and the inner surface of light pipe sleeve 140. The air then reaches a “ring” shaped galley between atomizer housing 232, cartridge 150, and light pipe sleeve 140. Air travels to proximal wick 234 via one or more holes 232-1, in chamfered surface(s) 232-1. Air is also allowed to enter cartridge 150 via one or more channels 154. This air entering cartridge 150 via channels 154 “back fills” for the substance being vaporized which enters proximal wick 234. The substance being vaporized is held in direct contact with proximal wick 234 by cartridge 150. The substance being vaporized is absorbed by and may saturate distal wick 243 and proximal wick 236.

The incoming air drawn through holes 232-1 displaces from saturated proximal wick 234 the substance being vaporized. The displaced substance being vaporized is pulled from wick elements 234 into a cavity between wick distal wick 234 and proximal wick 236. This cavity may also contain a heating element that has been heated to between 150-200° C. The displaced substance being vaporized is pulled from distal wick 234 in small (e.g., atomized) droplets.

FIGS. 76A-76S show various views of another vaporizer 76000 embodiment. In particular, FIG. 76A shows a perspective view of vaporizer 76000, while FIG. 76B shows a side view of vaporizer 76000. Vaporizer 76000 may have a housing 76002 comprising an oral aspiration tube 76004 for transporting vapor to a user's mouth. As the user's mouth aspirates at the oral aspiration tube 76004, taking in vapor, air may be taken into the vaporizer 76000 through air intake ports 76006.

A battery carrier sleeve 76008 may be slidably coupled with the housing 76002 for guiding alternative movement of the battery carrier sleeve 76008 between an extended position and a retracted position. The vaporizer 76000 may be electrically activated to produce vapor when the battery carrier sleeve is moved into the extended position. Vapor production may be suspended, and the vaporizer 76000 may be temporarily deactivated, when the battery carrier sleeve is moved into the retracted position.

The battery carrier sleeve 76008 may be disposed within the housing 76002. The housing 76002 may have an aperture 76010 extending into the housing 76002 and arranged adjacent to a surface of the battery carrier sleeve 76008. The surface of the battery carrier sleeve 76008 may be arranged so as to be manually accessible through the aperture 76010 by a user for controlling the movement of battery carrier sleeve 76008 between the retracted position and the extended position.

Vaporizer 76000 may comprise oral aspiration tube 76004, vaporizer assembly 76020, contact pellet 76034, bushing 76036, resilient member 76038 and battery contact post 76040. Battery carrier sleeve 76008 may be adapted for receiving a battery 76042. The battery carrier sleeve 76008 may comprise an air circulation vent 76043, which may extend through the battery carrier sleeve 76008 for cooling the battery 76042. Material of the battery carrier sleeve 76008 may be selected so that the battery carrier sleeve 76008 may have a high thermal conductivity, substantially greater than approximately ten Watts per Kelvin-Meter, for sinking heat from the battery during operation of the vaporizer. Further, material of the battery carrier sleeve 76008 may be selected so that the battery carrier sleeve 76008 may have a very high thermal conductivity, substantially greater than approximately one-hundred Watts per Kelvin-Meter, for sinking of heat from the battery during operation of the vaporizer. For example, the battery carrier sleeve 76008 may comprise aluminum.

More specifically, the battery carrier sleeve 76008 may receive battery 76042 having positive and negative polarity battery terminals 76044, 76046, and battery contact post 76042 may be arranged for electrically coupling with either battery terminal 76044, 76046, independent of any polarity of either battery terminal 76044, 76046.

FIG. 76D shows a detailed side view of vaporizer assembly 76020 and oral aspiration tube 76004. FIG. 76E shows a detailed perspective view of vaporizer assembly 76020. FIG. 76F shows a perspective exploded view of vaporizer assembly 76020 together with oral aspiration tube 76004.

As shown in the exploded view of FIG. 76F, the vaporizer assembly 76020 may comprise a cap 76021, an outer reservoir cover 76022, a resilient o-ring 76023, absorptive ceramic reservoir 76024, a supportive inner reservoir sleeve 76025, an atomizer assembly 76050 and a supportive atomizer fluid interface 76027. Cap 76024 may be removable, and in particular absorptive ceramic reservoir 76024 may removable by a user of the vaporizer, so as to provide for cleaning or replacement of the absorptive ceramic reservoir 76024

The oral aspiration tube discussed previously herein may be fluidly coupled with the atomizer assembly 76050 for transporting vapor from the atomizer assembly to the user's mouth. When electrically activated, atomizer assembly 76050 can change liquid into vapor. Absorptive ceramic reservoir 76024 may provide for volume storage of the liquid. For example, the liquid may comprises a miscible liquid, and the absorptive ceramic reservoir 76024 may be adapted for volume storage of the miscible liquid.

Absorptive ceramic reservoir 76024 may be fluidly coupled with the atomizer assembly 76050 for providing the liquid to the atomizer assembly 76050, in response to aspiration by the user. In particular, air intake ports 76006 may extend through outer reservoir cover 76022, and may be fluidly coupled with the absorptive ceramic reservoir 76024 for bubbling air into the absorptive ceramic reservoir in response to aspiration by the user.

A first set of liquid transport apertures 76026A may extend through supportive inner reservoir sleeve 76025, for transporting liquid aspirated from the absorptive ceramic reservoir 76024 through the supportive inner reservoir sleeve 76025. Similarly, a second set of liquid transport apertures 76026B may extend through supportive atomizer fluid interface 76027, for transporting liquid aspirated from the absorptive ceramic reservoir 76024 through the supportive atomizer fluid interface 76027. Similarly, a third set of liquid transport apertures 76026C may extend into atomizer assembly 76050, for transporting liquid aspirated from the absorptive ceramic reservoir 76024 into atomizer assembly 76050.

In other words, the first and second sets of liquid transport apertures 76026A, 76026B may form at least one liquid aspiration channel 76026A, 76026B, which may be fluidly coupled between the atomizer assembly 76050 and the absorptive ceramic reservoir 76024 for aspirating the liquid from the absorptive ceramic reservoir 76024 in response to aspiration by the user. As shown in exploded view in FIG. 76F, air intake ports 76006 and the liquid aspiration channel 76026A, 76026B may each be arranged at respective opposing surfaces of the absorptive ceramic reservoir 76024, so as to promote the aspiration of liquid from the absorptive ceramic reservoir 76024.

As shown in FIG. 76F, the absorptive ceramic reservoir 76024 may have a substantially annular cross section. The absorptive ceramic reservoir 76024 may be substantially cylindrically shaped. Atomizer assembly 76050 may be coaxially arranged with such substantially cylindrical shape of the absorptive ceramic reservoir 76024. As shown in FIG. 76F, resilient o-ring 76023 may be arranged adjacent to an extremity of the substantially cylindrical shape of the absorptive ceramic reservoir 76024, for providing at least some shock protection to the absorptive ceramic reservoir 76024.

As shown in FIG. 76F the substantially cylindrical shape of absorptive ceramic reservoir 76024 may comprise a cylinder wall having a thickness dimension “T”. To provide for volume storage of the liquid, and to provide for some strength of the absorptive ceramic reservoir 76024, the thickness dimension “T” may be greater than approximately a couple of millimeters. To provide for some user convenience and some compact thinness of the absorptive ceramic reservoir 76024, the thickness dimension “T” may be less than approximately tens of millimeters. Accordingly, the thickness dimension “T” may be within a range from approximately a couple of millimeters to approximately tens of millimeters.

To provide for some user convenience, and to avoid an excessive need to refill the absorptive ceramic reservoir 76024 continually, the absorptive ceramic reservoir 76024 may have liquid absorption volume of greater than approximately half a milliliter. In particularly, the absorptive ceramic reservoir 76024 may have a liquid absorption volume sufficient for more than approximately seventy-five full aspiration cycles through the user's mouth and substantially filling a user's lungs. To provide for some user convenience and some compactness of the absorptive ceramic reservoir 76024, the absorptive ceramic reservoir 76024 may have liquid absorption volume less then approximately ten milliliters. Accordingly, the absorptive ceramic reservoir 76024 may have a liquid absorption volume within a range from approximately half a milliliter to approximately ten milliliters.

The absorptive ceramic reservoir 76024 may comprise a macroporous ceramic. The macroporous ceramic may be substantially hydrophilic. Further, the macroporous ceramic may comprise a substantially open pore structured ceramic. Moreover, the macroporous ceramic may comprise a substantially interconnected macroporous ceramic.

The macroporous ceramic may comprise an oxide ceramic. More particularly, the macroporous ceramic may comprise Aluminum Oxide. Since the atomizer assembly 76050 may generate heat, to provide for some user safety the absorptive ceramic reservoir 76024 may be substantially a non-flammable. To provide for some safety of the user inhaling vapors of the vaporizer, the absorptive ceramic reservoir 76024 may be substantially chemically inert.

Parameters of the macroporous ceramic may be chosen so as to provide for some ease of use of the user aspirating the liquid from the absorptive ceramic reservoir 76024. The macroporous ceramic may have an air entry value within a range from approximately one fifth of a pound per square inch to approximately eight pounds per square inch. The macroporous ceramic may have a porosity within a range from approximately forty percent to approximately ninety percent. The macroporous ceramic may have an average pore size within a range from approximately twenty five microns to approximately one hundred and fifty microns.

In addition to providing some ease of aspiration, parameters such as porosity greater than approximately forty percent and/or average pore size greater than approximately twenty five microns may provide some wicking efficiency, in filling the absorptive ceramic reservoir 76024 with liquid. Parameters such as porosity less than approximately ninety percent and/or average pore size less than approximately one hundred and fifty microns may provide for some strength of the absorptive ceramic reservoir 76024. To provide some balance between ease of aspiration, wicking efficiency and strength, the macroporous ceramic may have an average pore size of approximately seventy microns.

Use of the previously described macroporous ceramic need not be strictly limited to the absorptive ceramic reservoir 76024. As will be discussed subsequently herein other vaporizer components may be comprised of the macroporous ceramic as just described.

To provide for some safety of the user inhaling vapors of the vaporizer, the splatter shield 76052 may be substantially chemically inert.

Parameters of the macroporous ceramic may be chosen so as to provide for some ease of use of air or vapor entry into the splatter shield 76052. The macroporous ceramic may have an air entry value within a range from approximately one fifth of a pound per square inch to approximately eight pounds per square inch.

In other words, FIG. 76P shows in cut away view the first and second sets of liquid transport apertures 76026A, 76026B, which may form at least one liquid aspiration channel 76026A, 76026B, and which may be fluidly coupled between the atomizer assembly 76050 and the absorptive ceramic reservoir 76024 for aspirating the liquid from the absorptive ceramic reservoir 76024 in response to aspiration by the user. As shown in cut away view in FIG. 76P, air intake ports 76006 and the liquid aspiration channel 76026A, 76026B may each be arranged at respective opposing surfaces of the absorptive ceramic reservoir 76024, so as to promote the aspiration of liquid from the absorptive ceramic reservoir 76024.

The absorptive ceramic reservoir of the vaporizer may be arranged for filling, or refilling, by the user dripping liquid. For example, FIG. 76Q shows a side view of vaporizer 76000, for illustrating filling or re-filling of the absorptive ceramic reservoir of the vaporizer 76000 with liquid, by dripping drops of liquid as show in FIG. 76Q down oral aspiration tube 76004. As shown in further detail in detailed cutaway partial view in FIG. 76R of the vaporizer, drops of liquid may flow through splatter shield 76052, and may flow through wick element 76057 of atomizer assembly 76050 as depicted by notional lines and associated arrowheads. As further depicted by notional lines and associated arrowheads in FIG. 76Q, liquid may flow from wick element 76057, out of atomizer assembly 76050 through the third set of liquid transport apertures extending into atomizer assembly 76050, through the second and first sets of liquid transport apertures forming the liquid aspiration channel, and into the absorptive ceramic reservoir 76024, so as to fill or refill the absorptive ceramic reservoir 76024 with liquid. Accordingly, the absorptive ceramic reservoir 76024 may be arranged with the liquid aspiration channel for filling or refilling the absorptive ceramic reservoir 76024 by disposing liquid into the liquid aspiration channel.

FIG. 76S is a detailed cutaway partial view of the vaporizer to illustrate aspiration of liquid into the atomizer assembly 76050, and to illustrate the atomizer assembly 76050 when activated to change the liquid into vapor. Air, as depicted in FIG. 76S by notional arrows, may be bubbled into the absorptive ceramic reservoir 76024 through air intake ports 76006 of outer reservoir cover 76022, in response to aspiration by the user. As depicted in FIG. 76S by notional arrows, liquid may be mixed with air and aspirated from absorptive ceramic reservoir 76024 through first and second sets of liquid transport apertures, which may form the liquid aspiration channel. The liquid aspiration channel may be fluidly coupled between the atomizer assembly 76050 and the absorptive ceramic reservoir 76024 for aspirating the liquid from the absorptive ceramic reservoir 76024 to the wick element 76057 and heating element support member 76058 of the atomizer assembly 76050, in response to aspiration by the user.

The aspiration channel may be coupled with the ceramic wick element 76057 for bubbling air into the ceramic wick element 76057 in response to aspiration by the user's mouth. The aspiration channel 76026A, 76026B may be coupled with the ceramic wick element 76057 for aspirating liquid into the ceramic wick element 76057 in response to aspiration by the user's mouth.

More generally, the aspiration channel may be coupled with absorptive member 76057 for bubbling air into the absorptive member 76057 in response to aspiration by the user's mouth. The aspiration channel may be coupled with absorptive member 76057 for aspirating liquid into the absorptive member 76057 in response to aspiration by the user's mouth.

As depicted in FIG. 76S by notional dashed arrows, vapors may flow from heating element support member 76058 when heated by electrical activation of heating element 76054 (and heated by heating element support member 78058), for changing the liquid into the vapors. Splatter shield 76052 may be fluidly coupled with lumen of the oral aspiration tube 76004 for substantially shielding the user's mouth from liquid splatter when the user's mouth aspirates the oral aspiration tube 76004.

Operation of vaporizer 76000 is depicted in various sequential views in FIGS. 77A-77F. In initial sequential side view, FIG. 77A shows vaporizer 76000, which may have housing 76002 comprising oral aspiration tube 76004 for aspiration by user's mouth. For illustrative purposes, a profile of the user's mouth is depicted using dashed lines. As discussed previously herein, battery carrier sleeve 76008 may be slidably coupled with housing 76002 for guiding alternative movement of the battery carrier sleeve 76008 between an extended position and a retracted position. The vaporizer 76000 may be electrically activated to produce vapor when the battery carrier sleeve is moved into the extended position. Vapor production may be suspended, and the vaporizer 76000 may be temporarily deactivated, when the battery carrier sleeve is moved into the retracted position.

The battery carrier sleeve 76008 may be disposed within the housing 76002. The housing 76002 may have aperture 76010 extending into the housing 76002 and arranged adjacent to the surface of the battery carrier sleeve 76008. The surface of the battery carrier sleeve 76008 may be arranged so as to be manually accessible through the aperture 76010 by the user for controlling the movement of battery carrier sleeve 76008 between the retracted position and the extended position. In FIG. 77A, the battery carrier sleeve 76008 is shown in retracted position. Similarly, the user's thumb, which is depicted in dashed line as engaging the surface of the battery carrier sleeve 76008, is likewise retracted. FIG. 77B is a detailed cut away partial view showing the battery carrier sleeve in the retracted position as in FIG. 77A.

In subsequent sequential side view in FIG. 77C, the battery carrier sleeve 76008 is shown in extended position for electrically activating the atomizer assembly of vaporizer 76000 to change liquid into vapor. Similarly, the user's thumb, which is depicted in dashed line as engaging the surface of the battery carrier sleeve 76008, is likewise extended. FIG. 77D is a detailed cut away partial view showing the battery carrier sleeve in the extended position as in FIG. 77C. Vapors produced by the vaporizer in response to such manual activation by the user are representatively illustrated in FIG. 77C by dashed arrows extending from oral aspiration tube 76004. The vapors depicted as dashed arrows are shown extending into the user's mouth in response to aspiration by user's mouth. For illustrative purposes, the profile of the user's mouth is depicted using dashed lines.

In subsequent sequential side view in FIG. 77E, the battery carrier sleeve 76008 is shown once again in retracted position for electrically deactivating the atomizer assembly of vaporizer 76000. Similarly, the user's thumb, which is depicted in dashed line as engaging the surface of the battery carrier sleeve 76008, is likewise retracted. FIG. 77F is a detailed cut away partial view showing the battery carrier sleeve in the retracted position as in FIG. 77E. FIG. 77F shows remainder aspirated vapors depicted as dashed line curls in the mouth of the user. For illustrative purposes, the profile of the user's mouth is depicted using dashed lines.

As particularly shown in FIG. 77D, the atomizer assembly 76050 may comprise first electrical contact 76051 (for example, including at least inner contact member 76051) for selectively conducting a flow of battery power from battery 76042 to the atomizer assembly 76050 when the battery carrier sleeve 76008 is in the extended position as shown in FIG. 77D. First electrical contact 76051 (for example, including at least inner contact member 76051) may selectively interrupt the flow of battery power from battery 76042 to the atomizer assembly 76050 when the battery carrier sleeve 76008 is in the retracted position, as shown in FIGS. 77B and 77F.

As particularly shown in FIG. 77D, the battery carrier sleeve 76008 and battery contact post 76042 may be arranged for electrically coupling battery terminal 76044 of battery 76042 with contact pellet 76034 and first electrical contact 76051 of the atomizer assembly 76050, when the battery carrier sleeve 76008 is in the extended position. Battery carrier sleeve 76008 and battery contact post 76042 may be arranged for electrically isolating the battery terminal 76044 from contact pellet 76034 and first electrical contact 76051 of the atomizer assembly 76050, when the battery carrier sleeve 76008 is in the retracted position, as shown in FIGS. 77B and 77F. In particular, when the battery carrier sleeve 76008 is in the retracted position as shown in FIGS. 77B and 77F, there may be an air gap interposed between the battery contact post 76042 and contact pellet/first electrical contact 76034, 76051 of the atomizer assembly 76050, for electrically isolating battery contact post 76042 from contact pellet/first electrical contact 76034, 76051. As shown in FIGS. 77B, 77D and 77F, bushing 76036 may retain contact pellet 76034 in electrical coupling with the first electrical contact 76051 of the atomizer assembly 76050 (for example, with the extremity of inner contact member 76051 of the atomizer assembly 76050).

FIGS. 77B and 77F show expanded resilient member 76038, for example expanded spring 76038, which may be disposed within the housing sleeve 76048 and bushing 76036. Resilient member 76038 may be coupled with the battery carrier sleeve 76008 for urging the battery carrier sleeve 76008 into the retracted position, as shown in FIGS. 77B and 77F. FIG. 77D shows resilient member 76038 as compressed, for example compressed spring 76038, when battery carrier sleeve 76008 is in the extended position shown in FIG. 77D.

In other words, FIGS. 77A-77F show operation of an electrical switch comprising battery carrier sleeve 76008 slidably coupled with the housing for guiding alternative movement of the battery carrier sleeve 76008 between an extended position and a retracted position. The electrical switch may be closed for activating the atomizer assembly 76050 to change the liquid into the vapor when the battery carrier sleeve 76008 is in the extended position. The electrical switch may be open for deactivating the atomizer assembly 76050 when the battery carrier sleeve 76008 is in the retracted position. The electrical switch may be manually controllable by the user of the vaporizer, by manual control of the movement of the battery carrier sleeve 76008.

The electrical switch may be a momentary on-off switch. Momentary on-off switch may be “on”, as shown in FIG. 77D, so long as the user may hold the battery carrier sleeve 76008 in the extended position, against restoring force of compressed resilient member 76038 (in other words, against restoring force of compressed spring 76038.) Momentary on-off switch may be “off”, as shown in FIGS. 77B and 77F, so long as the user may relax hold on the battery carrier sleeve 76008, so that battery carrier sleeve is restored to retracted position, by restoring force as resilient member 76038 expands (in other words, as spring 76038 expands.) Accordingly, the electrical switch may be normally open, until closed by operation of the electrical switch.

FIG. 78 shows an alternative embodiment, which is generally similar to the other embodiment just discussed for FIGS. 76A-76S and 77A-77F, except that in the alternative embodiment of FIG. 78, the previously discussed resilient member may be omitted. In the alternative embodiment of FIG. 78, magnetically opposing magnetic members 78034, 78040 may provide the restoring force to urge the battery carrier 78008 back into the retracted position. In other words, contact pellet 78034 and battery contact post 78040 may be magnetized and arranged with magnetically opposing and magnetically repulsive polarities. Notional arrows are shown in FIG. 78 to depict lines of repulsive magnetic force, for urging the battery carrier 78008 into the retracted position.

FIG. 79 shows another alternative embodiment, which is generally similar to the other embodiment just discussed for FIGS. 76A-76S and 77A-77F, except that in the alternative embodiment of FIG. 79, the previously discussed absorbent ceramic reservoir may be omitted (and associated outer reservoir cover, resilient o-ring 76023 and supportive inner reservoir sleeve may likewise be omitted.) Without the absorbent ceramic reservoir for volume storage of liquid, liquid capacity of the alternative embodiment shown in FIG. 79 may be different. For example, some liquid capacity may be provided by liquid disposed in the wick of the atomizer assembly.

Without absorbent ceramic reservoir, vaporizer 79000 shown in FIG. 79 may have a more slender housing 79002 coupled with oral aspiration tube 79004 for transporting vapor to a user's mouth. Battery carrier sleeve 79008 may be slidably coupled with the housing 79002 for guiding alternative movement of the battery carrier sleeve 79008 between extended position and retracted position. Vaporizer 79000 may be electrically activated to produce vapor when the battery carrier sleeve is moved into the extended position. Vapor production may be suspended, and the vaporizer 79000 may be temporarily deactivated, when the battery carrier sleeve is moved into the retracted position.

The battery carrier sleeve 79008 may be disposed within the housing 79002. The housing 79002 may have an aperture 79010 extending into the housing 79002 and arranged adjacent to a surface of the battery carrier sleeve 79008. The surface of the battery carrier sleeve 79008 may be arranged so as to be manually accessible through the aperture 79010 by a user for controlling the movement of battery carrier sleeve 79008 between the retracted position and the extended position.

FIGS. 80A and 80B show yet another alternative embodiment. FIGS. 80A and 80B are partial cutaway views showing oral aspiration tube 8004 and splatter shield 80052. FIGS. 80A and 80B particular show alternative rotation orientation side views oral aspiration tube 8004 and splatter shield 80052. FIG. 80A is oriented to show a narrow width dimension along a minor axis of splatter shield 80052. Air gaps shown in FIG. 80A, which may be defined between the oral aspiration tube 8004 and the narrow width dimension of the splatter shield 80052 may provide for vapor flow around the splatter shield 80052.

FIG. 80B is oriented a quarter turn relative to FIG. 80A, so as to show a broad width dimension along a major axis of splatter shield 80052. The broad width dimension of the splatter shield 80052 shown in FIG. 80B may provide for retention engagement of the broad width dimension of splatter shield 80052 by the oral aspiration tube 80004. The oral aspiration tube 80004 may be formed about the broad width dimension of splatter shield 80052 in retention engagement of the broad width dimension of splatter shield 80052. The oral aspiration tube 80004 may be coupled with the splatter shield 80052 so as to retain the non-flammable spatter shield 80052 with the oral aspiration tube 80004 when the oral aspiration tube 80004 is removed from the vaporizer.

FIG. 81 is a flow diagram of a vaporizer operation process 8100 according to one embodiment. In accordance with process 8100 shown in FIG. 81, the process may begin with providing 8102 solderless pressure contacts of a heating element. The process 8100 may continue with coupling 8104 a flow of power through the solderless pressure contacts to electrically activate the heating element. The process 8100 may continue with changing 8106 a liquid into a vapor in response to electrical activation of the heating element. The process 8100 may continue with interrupting 8108 the flow of power through the solderless pressure contacts to electrically deactivate the heating element. Once the flow of power through the solderless pressure contacts has been interrupted 8108, the process 8100 can end. FIG. 82 is a flow diagram of a vaporizer assembly process 8200 according to one embodiment. In accordance with process 8200 shown in FIG. 82, the process may begin with arranging 8202 a wick element proximate to a heating element having first and second extremities. The process 8200 may continue with arranging 8204 the heating element proximate to an inner contact member. The process 8200 may continue with applying 8206 a first pressure member to sandwich the first extremity of the heating element over said inner contact member to effect first solderless pressure electrical contacts. The process 8200 may continue with arranging 8208 the second extremity of the heating element proximate to an outer contact member. The process 8200 may continue with applying 8210 second pressure member to sandwich the second extremity of the heating element over said outer contact member to effect second solderless pressure electrical contacts. Once the second pressure member has been applied 8210, the process 8200 can end.

The advantages of the invention are numerous. Different aspects, embodiments or implementations may yield one or more of the following advantages. One advantage may be that soldering of the heating element may be substantially avoided. Another advantage may be that toxic lead and/or toxic lead vapors of lead based solder may be substantially avoided. Another advantage is that upon heating of the atomizer assembly, user inhalation of toxins from lead based solders may be substantially avoided. Another advantage is that solderless pressure contacts may provide ease or efficiency in assembly.

In an embodiment, direct writing of a conductive metal or conductive material to a heating element support member or wire guide, or other component which performs the function of a heating element can be used to construct a heating element or wire guide. Direct writing of these conductive materials or metals can be done instead of the metal wire and/or metal ribbon described previously herein. Direct writing expands the materials that can be used for the heating element beyond a metal wire or metal ribbon. In addition, metal deposition methods such as plating, electroplating, or sputtering can be used to make the same heating element and/or contact functionality as described hereinafter as performed through the implementation of direct writing methods. Likewise, the use of embedded metal into formed ceramic, or similar, components can be used to make the heating element and/or contact functionality as described hereinafter as performed through the implementation of direct writing methods. Embedded metals can be use facilitate electrical connection to direct written elements.

“Direct Writing” typically refers to a printing or patterning method that employs a computerized, motion-controlled stage with a motionless pattern generating device to dispense flowable materials in a designed pattern onto a surface. Conductive flowable materials (a.k.a., “inks”) that can be used in direct write applications include, but are not limited to: (i) polymeric—metallic particles in a polymeric matrix, primarily for polymeric substrates Silver, graphite, tungsten, copper; (ii) cermet—metallic particles in a glass matrix, primarily for ceramic substrates, gold, platinum, silver; (iii) nanoparticulate silver; and, (iv) specialty electrode materials such as titanium, stainless steel, niobium, and/or titanium nitride.

Substrates (i.e., surfaces) that can be used in direct write applications include, but are not limited to ceramics and metal. Examples of suitable ceramics include, but are not limited to: alumina, aluminum nitride, yttria-stabilized zirconia, and pyrex. Examples of suitable metals include, but are not limited to: Stainless steels (e.g., 316L, 302, 304 and 430), nitinol, and titanium alloys.

In an embodiment, a heating element is comprised of a conductive (flowable) material deposited on a substrate (support member). By depositing the heating element material on a support member, the heating element is now thermally coupled to the support member through the process of direct writing the heating element directly to the support member. The heating element is created using the process of direct writing can be substantially L-shaped etc., as described herein. For example, direct writing can be used to construct heating elements in place of wires and/or metal clips illustrated in FIG. 35A, FIG. 59A, FIG. 76K, and/or FIG. 76L. Taking FIG. 76K as an example, direct writing can be used to construct heating element 76054 on support member 76058.

FIG. 83 illustrates a perspective view of a directly written heating element disposed through a proximal wick element of a personal vaporizer unit. As shown in FIG. 83, a directly written conductor or heating element 839 may be wrapped around a portion of proximal wick 136 by running the conductor or heating element 139 at least part way into internal wire passageway 136-1, around the distal end of proximal wick 136, and through external wire passageway 136-2 to return to approximately its point of origin. In another embodiment, a directly written conductor or heating element 839 may be run primarily along external wire passageway 136-2 and not through internal wire passageway 136-1 (not shown in FIG. 76). The heating element 839 may, when personal vaporizer 100 is activated, heat proximal wick 136 in order to facilitate vaporization of a substance.

FIG. 83A illustrates an end view of contact points for a directly written heating element disposed through a proximal wick element of a personal vaporizer unit. Contact pads 831-832 to make electrical connections with heating element 839 may also be directly written to proximal wick 136. As shown in FIG. 83A, contact pads 831-832 are directly written to an end (e.g., proximal end) of wick 136. These contact pads are electrically connected to heating element 839 by directly written conductors and/or a portion of heating element 839.

FIG. 84 is a perspective view showing directly written heating elements disposed on the wire guides of FIGS. 54-58. As can be seen in FIG. 84, a directly written conductor or heating element 849 may be written on wire guide 237 and/or wire guide 238. Contact with heating element 849 may be made by directly written conductors connected to contact pad on the proximal end of wick 236. FIG. 84A illustrates an end view of contact points on a wick which supports wire guides having directly written heating elements. As shown in FIG. 84A, contact pads 841-842 are directly written to an end (e.g., proximal end) of wick 236. These contact pads are electrically connected to heating element 849 by directly written conductors and/or a portion of heating element 849 interfacing with directly written conductors on wick 236.

FIG. 85 illustrates two opposing side views of a wire guide that has a directly written heating element. As can be seen in FIG. 85, on one side of a wire guide 857 (e.g., wire guide 237), contacts pads 851 and 852 are directly written. When assembled, these contact pads 851-852 would be in direct contact with conductors on a wick (e.g., wick 236). On the other side of wire guide 857, an example directly written heating element 859 is illustrated.

FIG. 86 illustrates two opposing side views of a support element that has a directly written heating element. FIG. 86 illustrates a cylindrical support element. As can be seen in FIG. 86, on one side of a support element 867 (e.g., wire guide 237), a first contact pad 861 is directly written. A second contact pad 862 is placed on an end of the support element. On the other side of support element 867 from the first contact pad, an example directly written heating element 869 is illustrated.
